It has advantages like stick-slip-free operation, abrasion resistance, long service life, and compatibility with many temperatures and chemicals. The seal is recommended for injection molding machines, machine tools, presses, and floating piston accumulators. It uses a Turcon T46 seal ring and NBR or FKM o-ring depending on the application temperature.
